They work right out of the box.
We recently purchased two of these units for our northern home and found them to be reliable and decided to put one in our winter home.

Useless
Sitting 10 ft from it and it only has to filter dust and grasses. Not doing a darn thing.

Asthma Relief and PM2.5 filtration
Clean Air.. Galore.. Had some issues with allergies that were effecting my asthma, already using 1200 air handler filters needed to get a bit better air quality indoors. The BreathSmart 45i sure seems to help, put in automatic mode and let it do its thing filtering air throughout the day.

You wont be disappointed
One of the best purchases I've made. If you have any pets this is a must. No more pet odor. I like how it tells you the air quality with the top color panel

Love them!
I bought 2 of these earlier this year. Best purchase ever. I can breathe better now thanks to them. We live on a high-traffic road, so there is a lot of dust and pollen, and this air purifier literally filters most of the particles out automatically, and will indicate the air quality, then adjust on its own accordingly!!

its probably me
this may work, but I bought it to help remove the smell of a nail salon, its not working. it probably isn't the fault of this machine, I may be using it in the wrong way (yes I did remove the bag from the filter before turning it on lol) I was hoping it would reduce the smell, however it does not.

Works well
Love the look of this and that it’s customizable. It actually runs very quiet. I think it purifies the air pretty good so overall would recommend.
